How to troubleshoot no weld output and wire feed issues on my Miller Welding System?
- LLarry OliverAug 11, 2025
If your Miller Welding System has no weld output and the wire isn't feeding, ensure the line disconnect switch is On. Also, replace the building line fuse or reset the circuit breaker if it's open. Secure the gun trigger connections. Check the continuity of the power switch S1 and replace it if needed. If problems persist, a Factory Authorized Service Agent should check the main transformer T1 for winding failure and proper connections, including secondary voltages, and replace T1 if necessary. The agent should also check the continuity of thermostats TP4 and TP5, replacing them if needed. Finally, have the agent check the main control board PC1 and its connections, replacing it if necessary.
